Patented Apr. 2, 1940 UNITED STATES TYPE CASTING MACHINE MOUTI-IPIECE WIPER David Diamond, Brooklyn, N. Y.

Application February 1, 1939, Serial No. 254,080 10 Claims. (01. 199-62) The purpose of this invention is to provide a positively operated device for cleaning the mouthpiece of typecasting machines of the type in which the mouthpiece is in a horizontal position and moves over under the mold, and then back so that particles of type metal, dust and dirt remain on the upper surface thereof.

The invention is a device slidably mounted and connected to; the delivery slide of these machines so that it will move backward and forward across the mouthpiece as the delivery slide operates, thereby wiping the mouthpiece with a double movement each time the machine operates This particular machine, commonly known as a type casting machine, is ordinarily provided with a wiperin the form of a felt baffie hanging downward in the path of the mouthpiece so that the mouthpiece passes backward and forward, scraping the lower edge of the felt baffle, but this 20 is not very eificient because the felt is only sup ported from the upper edge and hangs downward, and soon curves outward so that it catches on the edge of the mouthpiece and is often pulled from its mounting at several points, so that it does not actually brush the exposed surface of the mouthpiece, and, therefore, particles of type metal and the like remain on the mouthpiece which prevents positive contact between the mouthpiece and. mold, and this causes unevenness 30 and even small flanges or extensions at the bottom of a line of type cast in the mold.

Many types of wipers have also been provided for line casting and other similar machines, and

some of these are positively operated, but any of 35 these could not be adapted for this machine because they are substantiallythe same as wipers used on the machine at the present time in that they'only involve a single strip of material or a flat pad, and this has not proved sufficient because the mouthpiece is horizontal, and the particles have a tendency to rest thereon instead of falling off by gravity as in line casting and other similar machines.

'I'heobject of this invention is, therefore, to provide a positive cleaner in the form of a scraper or brush for positively cleaning the exposed horizontal surface of the mouthpiece of type casting machines.

Another object is to provide a cleaner for the mouthpiece of type casting'machineswhich comprises a plurality of wiping elements.

Another object is to provide a cleaner for the mouthpiece of type casting machines which is resiliently held against the mouthpiece while cleaning. r

Another object is to provide a movable cleaner. for the mouthpiece of type casting machines which is positively operated by a part of the machine, such as the delivery slide.

A further object is to provide a positive movement for a cleaner of the mouthpiece of type casting machines in which a safety release is provided.

And a still further object is to provide a positive device for cleaning the mouthpiece of line casting machines which is of a simple and economical construction.

With these ends in view the invention embodies a cleaner comprising a plurality of strips of felt or the like positioned transversely of the mouthpiece of'a type casting machine, a carriage supporting said cleaner, means slidably mounting the carriage, and means connecting the carriage to the delivery slide of the machine.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure 1 is a view showing an outline of the upper part of a type casting machine, with the table top and other parts omitted. 5 r

Figure 2 is a view showing a side elevation of the cleaner Figure 3 1s across section through the bar upon which the cleaner is slidably mounted showing a front elevation of the cleaner and mounting and operating means.

Figure 4 is a plan view showing the device with the connecting means, and with a portion of the mouthpiece and also a portion of the delivery slide indicated in dotted lines.

In the drawings the device is shown as it may be made, wherein numeral] indicates thepad frame, numeral 2, the sliding carriage, numeral 3, a connecting link, numeral 4, the mouthpiece,

and numeral 5, the delivery slide.

The cleaner frame I is made as shown, with strips 6 of felt or a suitable absorbent material held therein by a plate I and screws 8, and the strips 6 are spaced apart by separating strips 9.

It will be understood that thestrips of felt or other suitable material may be arranged in any manner, held in any suitable frame, and any number of strips may be used, and the strips may be of any suitable size. The frame I is pivotally mounted on the carriage 2 through a bolt Ill in a hub II, and the side bar of the frame, which is indicated by the numeral l2, extends backward, forming, an extension l3 having a pin therein which engages a bevel surface I 5 of a lug l6 mounted at the end of a'bar l'l'upon which the PATE T OFFICE,

carriage is slidably mounted, and, as the carriage moves backward to the position shown in Figures 2 and 4, the pin l4 engages the surface 15 and moves downward, thereby causing the opposite end with the cleaning pad therein to move upward to the position shown in Figure 2, this movement elevating the pad above the surface of the mouthpiece. The frame i is also provided with a pin 18 at the forward end, and a spring I S mounted in a slot in a pin or lug 25 on the side of the carriage rests upon the pin is, resiliently holding the forward end of the carriage and pad downward against the surface of the mouthpiece when the pin Hi has travelled beyond the end of the lug Hi.

The carriage 2 is formed as shown in Figures 3 and 4, with inwardly extending flanges 2i and 22 extending into grooves in the under surface or at the sides of the bar ll, thereby holding the carriage upon the bar and permitting it to travel backward and forward thereon. The bar I! is rigidly mounted upon an upwardly extending member 23 of a member 24, forming one side of the track of the delivery slide 5. It will be understood, however, that the bar I! may be supported in any manner.

At the outer end of the bar I! is a lug 25 having a bevel surface 26 oppositely positioned to the lug It so that, as the carriage travels forward, the pin it will engage the surface 26, supporting the pad in the extreme position.

The carriage is also provided with a bearing 21' to which the link 3 is pivotally attached by a screw 28, and the opposite end of the link is pivotally attached to a clip 29 by a screw 39, and the clip 29 is attached to the end of the delivery slide 5 of the machine by a screw 3|. The link 3 is preferably provided with a slotted opening 32 in which the screw 30 is held, and the screw is held in this opening by a spring 33 which is arranged to permit the screw to pass out of the opening if the carriage or pad should strike an obstruction, thereby providing a safety release to prevent breaking any of the parts in case of an emergency.

It will be understood that changes may be made in the construction without departing from the spirit of the invention. One of which changes may be in the use of any means for slidably mounting the cleaning pad on the machine, another may be in the use of other means for operating the pad by a moving part of the machine or by other means, another may be in the use of a safety release of any other type, another may be in the use of a sliding carriage or track of any other design, and still another may be in the use of a spring of any other type or in the use of other means for resiliently holding the cleaning pad against the surface of the mouthpiece.

The construction will be readily understood from the foregoing description. In use the device is shown as mounted upon the bracket 23 by attaching the bar I? in place of the support for the wiper ordinarily used. and, with this in place, the carriage supporting the cleaning pad is connected by the link 3 to the delivery slide of the machine through a threaded opening in the end of the slide by placing a longer screw therein, and, as the delivery slide moves backward and forward, the link 3 will move the carriage 2 with the pad I thereon forward across the mouthpiece, indicated by the dotted lines shown in Figure 4, and, as the delivery slide moves forward and backward between each movement of the mouthpiece, the wiper operates with a double movement removing the rough particles with the forward movement, and then thoroughly cleaning the mouthpiece with the backward movement.
